METAL TILE.

Application filed August 10, 1925.

My invention relates to a new and useful improvement in tiles adapted particularly for use in floor and ceiling construction, although I do not wish to specifically limit myself to a tile for floor and ceiling con struction, it being my intention to bring within the scope of this invention the various uses in building constructions to which it may be put. Tiles of this class are generally used for supporting a concrete structure and in the construction of the buildings the tiles are first suitably arranged so as to be supported by a removable framework. The plastic material, such as concrete and the like, is then poured over the tiles and allowed to set before removal of the supporting framework. In the use of these tiles in constructing buildings, it is oftentimes desirable to project through the floors or ceilings of the buildings various structures, such as pipes, conduits, and the like. In passing these pipes, conduits, etc, over the top of the tiles, it is necessary that the tiles be broken away or mutilated so as to allow the space for the projection of these pipes, etc. In this connection it will be noted that it is desirable to have a uniform layer of concrete to provide a floor and that at the points where the pipes or conduits are projected through the structure this layer of floor-forming material should not be reduced in thickness and should not unduly be increased in thickness, so as to pr e serve the strength of the structure which is present in the uniformly distributed. floor layer. In the present invention I provide metallic tiles and have shown a metallic tile of a reduced size which may be used in conjunction with other tiles of larger size so that where the tile of reduced size is used there is provided a space for the projection of pipes, conduits, etc. The variation in the size of the tiles will depend upon the size of the conduits or pipes to be projected through the structure. The tiles of larger size will, however, remain uniform throughout the structure, the smaller tiles being used only at those places where it is desired to pass the pipes or conduits therethrough. It is an object of the present invention to provide a ceiling or building construction employing tiles which are so constructed as to provide for the necessary space for the rojection of pipes, conduits, etc., while at tie same time being easily and quickly assembled in relatively operative .erial No. 49,241.

position to the larger or standard sized tiles.

It is another object of the present invention to provide a metal tile provided with a top wall and side walls, the top wall having a space formed therein for the reception of the side Walls of a tile, the side walls of which project above and below the top wall ofthe tile.

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of parts hereinafter described and claimed.

The invention will be best understood from reference to the accompanying drawings, which form a part of this specification, and in which,

Fig. 1 is a fragmentary central vertical sectional view of the invention, showing it in operative position,

Fig. 2 is a fragmentary sectional view taken on substantially line 2-2 of Fig. 1,

Fig. 3 is a fragmentary sectional view of the invention taken on substantially line 3-3 of Fig. 1,

Fig. 4 is a fragmentary perspective view of the invention without corrugations,

Fig, 5 is a perspective view of cover used in the invention,

Fig. 6 is a perspective View of the cap. The larger tiles which determine the space between the floor 11 of one story and the plaster 13 of the ceiling below may, for the purposes of this description, be termed standard tiles, inasmuch as the space between the ceiling and floor described is in most places generally standard in buildings ofthe same size and construction on the same floors. These standard tiles are preferably made from metal and are formed with corrugated side walls 9 and a top wall 10, the plastic material 11 being poured thereon to provide the fleor. A bottomforming member 1 2 is secured to the tile 9 and provided with openings into which projects the plaster used for forming the ceiling 13. This bottomforming member, which may be termed a lathing unit, not specifically described, as it forms no essential partof the present invention. Before the pouring of the concrete to form the floor 11, the tiles are arranged in their desired position supported by suitable false work, which, after the concrete has set, is removed. This false work has not been shown as the method of erecting it is well lniown to thoseskilled in. the art.

As shown in Fig. 1, pipes 20 then are projected over the tile structure and to accommodate these pipes it is necessary that a space be provided above the tile structure and below the level of the floor layer, the lower edge of which is determined by the upper surface of the standard tiles. To provide this space I have constructed a tile having side walls 14 and 15, each of which is provided with an angularly turned flange 1% and 15 respectively. These side walls are connected by a top wall 17 in which are formed notches 16 and 16. In assembling the tiles, the smaller tile is selected for positioning in the proper position at the place desired to project the pipes 20. These smaller tiles are so constructed as to permit the end walls 9 of the standard tiles to enter into the slots 16 and 16, the end walls 1 1 and 15 overlapping the end walls 9, as clearly seen in Fig. 2. In this way the smaller tile serves as a closure for a portion of the end of the standard tile. To provide a closure for the remain ing portion of the end of the standard tile, I have constructed a cap 18 having flanges 19, this cap being adapted to fit over the end of the standard tile. Ihe reduced tiles will be of various sizes, the selection of the specific size being determined by the person constructing the building with a knowledge of the nature of the material, such as pipes, conduits and the like, which are to be projected through the structure. Where it is desired to project a large pipe through the structure, a small reduced tile would be used, and, oppositely, where it is desired to project only a small'pipe through the structure, a larger reduced tile would be used. It is consequently seen that there is a relation between the size of the reduced tile and the size of the cap, the tile and the cap to gether serving as an effective closure for the end of the standard tile so as to prevent the entry of concrete into the standard tile. A lathing unit 12 is also secured to the reduced tile. As shown in Fig. 5, the lathing unit has a doubled-over portion 1 1 which is adapted to embrace the flange 14: A nail 21 is driven through these telescoping parts so as to securely hold them together. As the concrete which flows. between the sides of adjacent layers of tiles sets around the nail 21, the nail becomes securely embedded in the concrete, and upon removal of the false work into which the end of the nail has been driven a slight distance, the driven end is then flattened over against the end surface of the member 12 or 12, as the case may be.

With the tile constructed as described, it becomes an easy matter to lay tile and provide quite securely for the necessary spaces required for pipes, conduits, etc. The assembly is a ready and quick one, which assures the proper construction and alignment of the various parts, while at the same time maintains the proper layer of concrete to provide the desired strength.

While I have illustrated and described the preferred form of construction, I do not wish to limit myself to the precise details of structure shown in the drawings, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A tile structure of the class described comprising a pair of trough shaped tiles placed end to end in inverted position, one of said tiles being higher than the other; and a cap mounted on said higher tile for closing the portion of its end projecting above the lower tile.

2. A tile structure of the class described, comprising an open tile positioned in alignment at one end with a higher open tile, said lower tile being adapted for telescoping at said end slightly with said higher tile, and a cap mounted on said higher tile for closing the portion of its end projecting above said lower tile. 7

3. A tile structure of the class described comprising an open tile positioned in alignment at one end with a higher open tile, said lower tile being adapted for telescoping at said ends slightly with saidhigher tile; and a closure for closing the portion of the end of said higher tile which projects above said lower tile.

4. A tile of the class described, comprising side walls and a top wall adapted for use with a higher tile having side walls projected above and below said top wall of said lower tile, said top wall of said lower tile having notches formed in its edges at opposite sides for accommodating the side walls of said higher tile when in telescopic relation thereto.
